Abstract
An image forming apparatus includes an image bearing member; a charging device; an exposure device configured to expose intermittently for each unit area of the image bearing member charged by the charging device to form a latent image; a developing device configured to develop the latent image with developer; a signal output portion configured to output a first electric signal when the exposure device exposes a print area of the image bearing member, and output a second electric signal, which instructs the exposure device to shorten an exposure time per unit area more than an exposure time of the first electric signal, when the exposure device exposes a non-print area of the image bearing member; and a count portion, to which the first and the second electric signals are input from the signal output portion, configured to measure only the first electric signal without measuring the second electric signal.
